To all whom it may concern:

Be it known that I, JOHN B. DHOMERGUE, a residentof Pittsburg, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Pipe-Coverings; and I do hereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to pipe coverings and has special reference to suchcoverings which are formed from what is generally known as cattle hairfelt.

Heretofore, in the use of hair felt for pipe coverings it has beencommonly purchased for this purpose in full rolls or bales and then cutin strips or lengths of the proper width to extend around the pipe to becovered. These strips being cut to the desired length were then placedon the pipe and secured in place by twine, after which the othermaterials, such as paper and canvas were each applied in turn around thefelt, and thereby making several operations.

Hair felt is a very difficult materialto cut, especially at the point orplace where it is to be used, owing to the lack of facilities and space,and being easily disintegrated. lVhen subjected to considerablehandling, it fre quently happens that in getting it to the point of useand cutting the same there, serious waste is resulted.

The object of my invention is to overcome these difficulties andobjections in the use of hair felt in pipe coverings, and to providesuch a form of pipe covering, which will be cheap, simplel and efficientfor the purpose intended, will do away with the heavy handling of thebales or rolls of hair felt and the cutting of the strips for thecovering therefrom, and will enable the covering to be so arranged thatit can be easily and quickly applied at a great saving of labor andmaterial.

My invention consists, generally stated, in the novel arrangement,construction and combination of parts, as hereinafter more specificallyset forth and described, and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains toconstruct and use my improved pipe covering, I will describe the samemore fully, referring to the accompanying drawing, in which- Figure 1 isa perspective view showing my improved pipe covering. Fig. 2 is a sideview of the covering applied to a pipe and showing the same partly insection and laminated.v Fig. 3 is an enlarged cross-section of the pipe,showing one-half of the covering in sections and the other half in endelevation.

Like symbols of reference herein indicate like parts in each of thefigures of the draw mg.

As illustrated in the drawing, my improved pipe covering 1 is composedof a strip of hair felt, as at 2, a piece of canvas, as at 3, forforming the exterior of said covering, a piece of paper, as at 4C,between the said felt andsaid canvas, and extending across and betweensaid canvas and paper are a number of short lengths of twine, as at 5.

In the manufacture of my improved pipe covering l, the proper lengths ofthe twines 5 desired are laid upon the proper width of the canvas 3desired, the proper width of the paper 4 desired is laid on said canvasand over said twines, and the proper width of the felt 2 is then laid onsaid paper. The side edges of the paper et extend beyond the side edgesof the felt 2, as at 4. and the side edges of the canvas 8 extend beyondthe side edges 4t of said paper as at 3', while the ends of the shortlengths or pieces of twine 5 extend beyond the side edges 3 of saidcanvas 3, and are of suflicient length for eX- tending around the feltand paper for tying when the covering is applied, as hereinafterdescribed. When the felt 2, canvas 3, paper t and twines 5 have beenthus placed in position, they are connected together by a central lineof stitching, as at 6, which passes through the felt, canvas and paperand around the twines, such sewing being performed in any suitablemanner and preferably by machinery. After my improved pipe covering lhas been thus formed and it is desired to apply the same around a pipea, it is cut to the length desired at either or both of its ends andthen the side of the same carrying the layer of hair felt 2 is placedagainst such pipe. After this is done the side edges of the felt 2 andpaper are bent around the pipe a and will be held in place by the handwhile the twines 5 are tied around the said paper and felt, as shown at5, and so actto draw the felt edges together and the edges t on saidpaper to overlap each other, as at 7, and thereby hold said felt andpaper around said pipe. `When the felt 2 and paper l are thus in placearound the pipe a, the canvas 3 is then turned over the felt and paper'which will allow the side edges 3 on the canvas 3 to overlap each other,as at 8, so that they can be connected together' at such edges bypasting or in anyl other suitable manner, and thereby bind the felt andpaper together around the pipe.

It will thus be seen that my improved pipe covering` can be easily andcheaply manufactured and can be furnished in the exact amount requiredfor each particular job, while it can be easily and conveniently shippedfor use in the fiat or in rolls and bales, and can be speedily andreadily applied with all its component parts at one operation. It willalso be seen thatthe covering will provide for making up hair felt in aconvenient form for ready and instant application and use with the othermaterials usually associated with the same, and all fastened together ina simple and practical manner. The central fastening of the partstogether enables all the materials to be held together7 while at thesame time they can slip on each other so that they can be bent aroundthe pipe to form the finished piece of work as well as permit the sameto be rolled up for shipping, packing or storage. By the use of thelayer of' papel' between the layers of' felt and canvas the face of thecovering formed by such canvas will form a smooth and finishedappearance to the eye and work7 and such paper being imperforate andwaterproof will assist the covering in retaining and protecting itsinsulating qualities.

It will be evident that other flexible insulating materials can besubstituted for the hair felt7 as well as other material for the paperand canvas, and that various other devices or means can be used forattaching the side edges of the felt, paper or canvas together, while itis also evident that the covering can have the paper and inclosingcanvas jacket dispensed with, and the felt alone used with the securingtwines or other means such as wires stitched thereto, while with thetwines held by the central longitudinal seam extending across the sainewill enable them to be placed within the rolls or bales of the cover'for packing or shipping. It will further be evident that the operationof forming the covering can be varied, and that if desired the tyingmeans Jfor the same can be arranged so that each of the materialscomposing the covering` can be furnished with its own twines andstitched by a single seam for securing each part separately around thepipe and all the parts ot' the same together.

Various other changes in the arrangement and construction of my improvedpipe covering may be resorted to7 without departing 'from the spirit ofthe invention or sacrificing any of its advantages.
